Ontology-based Virtual Query System for the SemanticLIFE Digital Memory Project : Concepts , Designs and Implementation

— Ever increasing capacities of contemporary storage devices inspire the vision to accumulate (personal) information without the need to delete old data over a long time-span. Hence the target of the SemanticLIFE project is to create a personal information management system for a human lifetime data. One of the most important characteristics of the system is its dedication to retrieve information and data in a very efficient way by adopting user demands regarding the reduction of ambiguities aiming at a user-friendly and yet powerful enough system with a satisfactory query performance. In this paper, we introduce the concepts and a design of the query system of SemanticLIFE, the Virtual Query System, which uses emerging Semantic Web technologies to fulfill necessary requirements.
